DIGITAL CINERADIOGRAPHIC STUDY OF SWALLOWING IN PATIENTS WITH AMYOTROPHIC LATERAL SCLEROSIS
Purpose. This study was performed to evaluate the usefulness of digital cineradiography in detecting swallowing disorders in dysphagic patients affected by amyotrophic lateral sclerosis (ALS) with a view to planning an adequate therapeutic approach. Material and methods. From January 2005 to September 2006, 23 patients (10 men and 13 women; mean age 41.3±8.6 years) affected by ALS were evaluated with digital cineradiography to assess the grade of dysphagia. All patients were classified using the Hillel ALS Severity Scale (ALSSS). All examinations were performed with radiocontrolled equipment provided with a digital C-arm. Results. The cineradiographic technique enabled us to differentiate p…

Virtual bronchoscopy in patients with central endobronchial stenosing lesions. Technique optimisation with single slice spiral CT.
PURPOSE: To describe an original protocol for single slice spiral Computed Tomography (CT) virtual bronchoscopy in the evaluation of patients with central airway stenoses and compare the results with fibreoptic bronchoscopy. MATERIALS AND METHODS: Ten patients (4 female and 6 male; age range 22-60 years; mean age 44 years) with endobronchial disease diagnosed by fibreoptic bronchoscopy (8 malignant tumours, 1 benign tumour and 1 fibroid stenosis) underwent virtual bronchoscopy with single slice spiral CT. A panoramic spiral CT scan of the whole chest was first obtained. Once the area of interest had been identified, a new contrast enhanced scan was performed, from bottom to top, with the fo…

Hepatocellular cancer response to radiofrequency tumor ablation: contrast-enhanced ultrasound
Radiofrequency ablation (RFA) is increasingly being used as percutaneous treatment of choice for patients with early stage hepatocellular carcinoma (HCC). An accurate assessment of the RFA therapeutic response is of crucial importance, considering that a complete tumor ablation significantly increases patient survival, whereas residual unablated tumor calls for additional treatment. Imaging modalities play a pivotal role in accomplishing this task, but ultrasound (US) is not considered a reliable modality for the evaluation of the real extent of necrosis, even when color/power Doppler techniques are used. Recently, newer microbubble-based US contrast agents used in combination with grey-sca…

Dislocazione infero-mediale del frammento meniscale. Studio con risonanaza magnetica
Definire l'accuratezza diagnostica della Risonanza Magnetica (RM) nella diagnosi di dislocazione infero-mediale del frammento della fibrocartilagine meniscale, Materiale e metodi. Sono stati valutati retrospettivamente gli esami RM del ginocchio, effettuati nel periodo compreso tra dicembre 2002 ed aprile 2004, di 676 pazienti (eta media 32 anni) affetti da patologia traumatica del ginocchio e successivamente sottoposti ad artroscopia, al fine di identificare la presenza di una lesione meniscale a manico di secchio e della dislocazione infero-mediale del frammento meniscale. Gli esami RM sono stati eseguiti con un magnete superconduttivo da 0,5 T utilizzando una bobina ricevente/trasmittent…

MR Imaging of Uterus Didelphys Transverse Vaginal Septum Causing Hematometrocolpos and Renal Agenesis
The association of uterus didelphys and unilateral blind vagina with ipsilateral renal agenesis is an infrequent urogenital malformation distinguished by a lesion of the mesonephric duct. In most patients, symptoms are present at the beginning of the menstrual cycle because a transverse vaginal septum on one side obstructs the flow of menses, which consequently collect. Magnetic resonance imaging allows a precise delineation of this congenital abnormality, clearly demonstrating the transverse vaginal septum with hematometrocolpos and uterus didelphys. Extending the magnetic resonance study to the abdomen and employing coronal sections with a wide field of view is important to search for ass…

Characterisation of focal liver lesions undetermined at grey-scale US: contrast-enhanced US versus 64-row MDCT and MRI with liver-specific contrast agent
The aim of this study was to assess the role of contrast-enhanced ultrasonography (CEUS) in the characterisation of focal liver lesions in comparison with multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) with liver-specific contrast agent.One hundred and eighty-seven focal liver lesions, 91 malignant and 96 benign (mean size 3.2 cm) - proved by biopsy (n=12), histology (n=4), MDCT (n=108), MRI (n=44) MDCT/MRI (n=19) - in 159 patients were studied by CEUS. Two expert radiologists consensually evaluated the contrast-enhancement patterns at CEUS. For each lesion, they assessed: (a) nature (benign, malignant, not assessable), (b) specific diagnosis and (c) need for …

Preliminary 1H NMR studyon waterlogged wood strengthened with Klucel
Waterlogged woods from sea or lakes are very fragile because chemical, physical and biological decay. Wood artefacts, if directly dried in air, risk a structurally collapse and loss original form and dimension. The progressive substitution of water with suitable strengthening materials can preserve the characteristic of the wood finds. Among various natural and synthetic polymers suitable for this porpoise we have chosen aqueous solutions of Klucel (hydroxypropylcellulose), a polymer obtained from etherification of cellulose. This compound can interact with all the components of the wooden structure (cellulose, hemicellulose and lignin) and can cover the cavities by a protective and stabili…
